[away3d] Mouse Interaction in Broomstick after setting View Size

[Snownova]

I've been playing around with Broomstick over the past few days, and
I've run into a problem when trying to set a size for my View3D
element. here is a basic version of the example InteractionTest to
demonstrate my problem:

package {

        import away3d.containers.View3D;
        import away3d.events.MouseEvent3D;
        import away3d.materials.BitmapMaterial;
        import away3d.primitives.Plane;

        import flash.display.Bitmap;
        import flash.display.BitmapData;
        import flash.display.BitmapDataChannel;
        import flash.display.Sprite;
        import flash.events.Event;
        import flash.geom.Rectangle;

        [SWF(width="800", height="450", frameRate="60")]
        public class InteractionTest extends Sprite     {
                private var _view:View3D;

                private var _mesh1:Plane;
                private var _material1:BitmapMaterial;

                public function InteractionTest() {

                        _view = new View3D;
                        _view.width = 800;
                        _view.height = 450;
                        _view.antiAlias = 4;
                        this.addChild(_view);

                        var bitmapData1:BitmapData = new BitmapData(512, 512, 
false,
0x000000);
                        bitmapData1.perlinNoise(64, 64, 5, 0, false, true,
BitmapDataChannel.BLUE);
                        _material1 = new BitmapMaterial(bitmapData1);
                        _material1.bothSides = true;

                        _mesh1 = new Plane(_material1, 500, 500, 1, 1);
                        _view.scene.addChild(_mesh1);
                        _mesh1.rotationY = .01;
                        _mesh1.mouseEnabled = true;
                        _mesh1.mouseDetails = true;
                        _mesh1.addEventListener(MouseEvent3D.MOUSE_MOVE, 
onMouseMove);

                        this.addEventListener(Event.ENTER_FRAME, 
handleEnterFrame);
                }

                private function onMouseMove(event:MouseEvent3D):void {
                        var material:BitmapMaterial = event.target.material;
                        var rect:Rectangle = new
Rectangle(event.uv.x*material.bitmapData.width-4,
event.uv.y*material.bitmapData.height-4, 9, 9);
                        material.bitmapData.fillRect(rect, 0x00ff00);
                        material.updateTexture();
                }

                private function handleEnterFrame(ev:Event):void {
                        _view.render();
                }
        }
}


When I set _view.width and _view.height, the mouse interaction appears
to be quite a bit to the left and up from where the cursor actually
is. When I don't set the widht and height properties for the View3D,
it works just fine, but my view extends beyond my swf and is scaled
and centered improperly.

Does anyone have any suggestions as to how to fix this?
